Research

My research interests are fluid mechanics applied to geophysics and astrophysics. For example, how the Earth's magnetic fields are generated and evolve, how tides in binary stars work, why proto-planetary or black hole disks become unstable, how turbulence behaves in the presence of rotation or stratification or magnetic fields, etc. To understand these physical problems, some mathematical equations need to be solved, and the methods involve analytical, semi-analytical and small-scale numerical calculations. Below are some objects that I study (from left to right: Earth's magnetic fields, Jupiter's red spot, stellar interior, tides in binary stars, and disk accretion).
